I was just watching the first three X-Men movies - I spotted him on the beach in the first one, and of course the hose scene in the third, but missed him in the second one. I'll have to pay attention when I rewatch "Wolverine."

I know there's a YouTube video of all his cameos, but is there a list, too?

Mirage, that's what I was thinking. That or he's lucky not to be indefinitely detained at an undisclosed location. Well, come to think of it, does anyone know where the "POW" offices are, or if they ever let him out? :)
